I guess it should read "adds time tracking integration".
And also not imply that it's Slack the company adding something to their product, but actually you who wrote an add-on for it.
That might be how you read it. It wasn't my intention to mislead, but to make people aware of the fact that there's a new time tracking integration (the first actually) which I know lots of people would value.
It's useful to be able to just track time directly from Slack, e.g "/start development", and I'm glad to finally have an app that does it.
You're glad you finally made the app that does what you want it to do...?
